关键性突破！“地表超强材料”

Core Viewpoint - The successful completion and production of a high-performance carbon fiber project in Shanxi marks a significant breakthrough in the domestic mass production of T1000-grade carbon fiber, which is crucial for various high-tech and defense applications [1][3][5]. Group 1: Project Overview - The high-performance carbon fiber project in Datong City, Shanxi, has completed construction and is now in production, achieving a key milestone in the domestic mass production of T1000-grade carbon fiber [1][5]. - The first phase of the project will have a demonstration production line with a capacity of 200 tons per year, set to commence full construction in June 2024 and complete by November 30, 2025 [5]. Group 2: Material Properties - The T1000-grade carbon fiber produced has a single filament diameter of only 6 to 7 micrometers, less than one-tenth the thickness of a human hair, yet boasts a tensile strength exceeding 6400 MPa [5]. - This carbon fiber has a density that is only one-fourth that of steel, while its strength is over five times greater than that of steel [5]. - A one-meter long bundle of this carbon fiber weighs just 0.5 grams but can support a load of over 200 kilograms, showcasing its exceptional strength-to-weight ratio [5]. Group 3: Applications and Significance - The T1000-grade carbon fiber integrates core advantages such as high strength, lightweight, high and low-temperature resistance, corrosion resistance, low friction, and good thermal and electrical conductivity, earning it the title of "the strongest material on Earth" [5]. - The project is expected to reduce reliance on imported high-end carbon fibers and has significant implications for national strategic material security, with applications in defense, aerospace, rail transportation, and low-altitude economy sectors [3][5].
